IMPROVEMENT IN PLANING--MACHINBS.

TO ALL WI-IOM IT MAY CONCERN':

Be it known that I, HORACE G. McDUFFE, of Bradford,in the county`ofOrange, and State of Vermont,

have invented a new and improved Machine for Planing Shingles,Clapboards, Ste. andI do hereby declare the following to be a full,clear, and exact description oi' the same, reference being had to theaccompanying drawings forming part of this specification, and in which-Figure 1 is a perspective view of my invention.

4Figure 2 is a longitudinal section ofthe shingle-beds O P, and

Figure 3 is a cross-section ofthe shingle-beds and the clapboard-bed R.

A'.Ihe subject oi'this invention is the machine for planing-shingles,clapboards, 36e., in which an endlessapron carrier is used.

' My invention consists in employing a series of beds on tn'e'surfaceofthe carrier, which hold, guide, and

govern the shaping and bevel ofthe shingles or clapboards as they passunder the planer.

Similar letters of reference indicate corresponding parts in the severalfigures.

In the drawings, A B C D E F GYY Y indicate the several parts oftheframe ofthe machine, '.I being the endless apron, composed ofrectangular plates or sections, united byhinges along' their inneredges, and running on hexagonal rollers inside of the frame, and notseen in the drawings. X is the planer, and Z Z are theguide-rollers,working above the apron T. The whole machine is operated by powerapplied atl the pulley I on the planer-shaft, and thence carried by abelt from the opposite end, H, of the shaft, to a pulley, L, and thence,

to a pulley, M, the shaft of which drives the apron '.l by a cog-gear,ttt.

The upper or outer surface of the apron I divide by longitudinal Vandtransverse ribs-r1' r, so as' to form rectangular beds 'or depressionson the surface of the apron between the ribs, to receive and hold theshingles, elapboard, 86e., and carry them under the planer. The beds areof the size ofthe shingles or clapboards to be sawed. Those designed forshingles are deep at one end, as at fl, figs. 1 and 2, and shallow atthe opposite end,

as shown at e. Those designed for the 'clapboards are deep on one sideand shallow o'n the other, as shown at tu,

iig. 3, the ends being of equal depth and dimensions. The shingle-orclapboard is'placed in its bed, fitting closely `down to the bottom'ofit, and in that position is carried by the apron under the planer, whichpasses horizontally over it, cutting it down to the level of the top ofthel ribs r 1', or` thereabout, and leaving the shingle or elapboardshaped like the bed in which it lay. As the apron emerges from beneaththe planer and guide-rollers and passes over` thc wheel at the end ofthe machine, it drops the shingles, and the beds are ready, when theyarrive at the' top ofthe machine, again to receive a new supply ofshingles.

It is evident that beds or depressions such as are above described, andfor the purpose abo've set forth, may be used aswell upon a carrierwhich has not the motion of an endless apron, but moves back and forthunder the planer, as upon the apron above described. I do notl wish tolimit myself to their use in connection with the endless-apron form ofcarriage, but p What I do claim as new, and desire to secure by LettersPatent, is-

In a planing-machine, as above described, a carrier, having its upper orouter surface formed into a. series` of beds or depressions, O P R, inshape the same as the shingle or clapboard to be planed,when'constructed andfoperating in combination with the planer X,substantially as and f 'or the purpose set forth.
